Influence of the war in Croatia on the frequency of gynecological cancer in the University Hospital Osijek in the period from 1985 to 2002.

The aim of this study is to estimate the influence of war in Croatia on the frequency of gynecological cancer (cancer of corpus and cervix uteri and ovary) in the Clinical Hospital Osijek, particularly the relation between the pre-war and post-war period. We analyzed 1455 patients with corpus uteri and cervix uteri cancer and ovarian cancer treated in the Clinical Hospital Osijek in the period 1985-2002 (group I). Patients from Osjecko-Baranjska County were analyzed separately--1273 women, (group II) and in the group III there were 182 patients from other counties. The analyzed period was divided into: pre-war 1985-1990, war 1991-1993 and post-war period 1997-2002. In all three groups the number of patients treated for gynecological cancer was significantly larger in the post-war period (group I, N = 611, group II, N = 498, group III, N = 113) than in the pre-war period (group I, N = 457, group II, N = 433, group III, N = 24). The analysis of cancer frequency in relation to the site shows that a total number of patients treated for cervical cancer was larger in the post-war (N = 229) than in the pre-war period (N = 214), but the difference wasn't significant. However, the number of patients from Osjecko-baranjska County treated for cervical cancer was larger in the pre-war (N = 207) than in the post-war period (N = 178) but still, the difference wasn't significant. The number of patients treated for corpus uteri cancer and ovarian cancer was significantly larger for the I group in the post-war (N = 225 and N = 157 respectively) than in the pre-war period (N = 136, and N = 107 respectively). In the group II the number of patients treated for corpus uteri cancer and ovarian cancer was larger in the post-war (N = 196 and N = 124 respectively) than in the pre-war period (N = 130 and N = 96 respectively) but the difference was significant only for corpus uteri cancer. Significantly more women were treated for gynecological cancer in the post-war than in the pre-war period. However, the war had probably an indirect influence on the increased number of patients treated for gynecological cancer mainly because many more women arrived from other counties.
